Definitions

  • the present invention relates to a lubricating device for motor-actuated extendible motor-car antennae.
  • the protective tubular covering of the telescope antenna is closed up toward the gear side by a stopper which by the grease pressure in the interior of the protective tubular covering is pressed in grease-tight fashion against the conveying means of the antenna which traverses it.
  • the result is that the grease passing through the center tube in downward direction is now caused to pass under continued grease-gun-pressure between the telescopic tubes in upward direction, whereby all of the dirt is carried along by it.
  • the pressing-in of the grease can be continued until perfectly clean grease emerges from the gaps between the telescopic tubes. In this manner it is possible in the simplest way to remove the dirt from the telescopic tubes. Until now the dirt inevitably adhering to the extended antenna could only difliculty be removed and was the source of constant trouble .of the mechanism of the antenna. This source of trouble has now been removed by the invention.
  • the reference numeral 2 designates the protective tubular outer covernited States atent ice ing secured to the car-body 6 by means of the clamping screw 3.
  • the innermost part 4 of the antenna has been devised as a tube, which tube has the spring-pressed ball 5 positioned in its end, whereby the ball 5 acts as a valve for the lubricating grease pressed in from above.
  • an ornamental cap or the like may be pushed or screwed.
  • the grease pressed into the tube 4 passes through the bore 17 in the lower end of the tube 4.
  • a stuifing box consisting of a stopper 8 and of the slotted tensioning screw 9 with the aid of which the conveying means, a 'nylonwire10, is closed up in greasetight fashion.
  • the pressure of the lubricating greases augmented by the pressure exerted by the collar-like portions of the stopper 8, increase the packing or tightening effect.
  • Continued pressure by means of the grease gun then causes the grease to rise in the space between the tubes 411 and 1112 and 1213 in upward direction until it finally escapes from the telescope at 14, 15 and 16, taking all of the dirt along with it.
  • Lubricated telescopic antenna comprising, in combination, an outer tubular casing; a plurality of slidable telescopic tubes having a contracted position in which said tubes are located in said casing with one end portion of each tube projecting from one end of said casing, said projecting end portions slidably engaging each other, adjacent tubes forming annular lubricating spaces open a the other ends of said tubes, the innermost tube of said tubes having a lubricating opening at its projecting end portion and an outlet opening at its other end; and closure means sealing the other end of said casing so that a lubricating medium pressed into said lubricating opening and through the interior of said innermost tube and said outlet opening into the sealed other end of said casing, passes through said annular spaces and out of the same in the region of said projecting end portions of said tubes whereby dirt is removed from said annular spaces to facilitate sliding movement of said tubes to an expanded position.
